Supercharger Belt size help

[Av3ng3d]

Hi guys I checked out the belt chart at https://stangshiftergaskets.com/belt_length_chart.htm and just wanted to verify this information is correct before purchasing a belt for my setup. I recently purchased the car and want to get a new belt on it before sending it off for a tune for the posi ported Eaton setup.
The car has a 2.93 upper with 4lb lower, a metco auxiliary pulley and what measured out to be a 3.75" alternator pulley.
Does an 80" belt sound about right? Also if anyone has any suggestions on preferred brand belt to go with I'm all ears.
Thanks in advance!

Did you change any of the pullies? If you're just looking to get a new belt and the current one fits correctly why not measure your current belt?

It’s either gatorback or gates. Think I’ve had a little better luck with the gator back not squealing when cold at times.

Your belt should have numbers on it. Just google and you’ll get the size.
